Just purchased a 04 2500. There's a black plastic box beside the power steering pump. What is it? I tried to open it but, it didn't want to. I thought maybe it was the heater cord. Thanks!
THe only thing i can think of that is in that area is the ecm(engine controle module) and the tcm (trans controle module) is on the fan shroud in front of that!
BTW, WElcome to the site! What part of PA are you from?
